Question

A girl jumps down from a tree to the grass below. The higher her jump,_______.

Answer 1

Answer:

D. The more the change in gravitational potential energy.

Explanation:

From Physics, we know that change in gravitational potential energy ($\Delta U_{g}$), measured in joules, is directly proportional to change in height ($\Delta h$), measured in meters. Then, the higher her jump, the more the change in gravitational potential energy.

We cannot speak of elastic energy, since statement of the problem does not speak of any deformable system (i.e. spring) in any form.

Therefore, the correct answer is D.
